I prefer FS-UAE over other ARM emulators due to the cycle-exact mode among other things and the good RPi 4 performance is interesting!
Has anyone tested FS-UAE with cycle-exact mode enabled and can report back? A500? A1200? With VSync?
I'm wondering which ballpark the RPi 4 is in exactly...
I found this
blog post. There's this comment there:

From Wikipedia I estimated BCM2837B0 (3 B+) at 1000 CPUmark. Raspberry Pi claim BCM2711 is 50% faster [sic: -> swifter], despite the integer benchmarks on this post, so that should be 1500 CPUmark, still 3/8 of the 5W and 4·5W CPU ultrabook speeds that folk said were too slow (not sure for what), on the i5–8200Y and i5–7Y57. 1500 is better than 3W SH-X4 RP-X, worse than Cortex-A53-A57 Typhoon A8, worse than 4W Atom Broxton T5700, worse than 7·5W Pentium Bay Trail-M N3540, and almost equivalent to 25W Core 2 Duo Penryn P8700.
I still need the CPU’s TDP tho; the last one was 3·5W. If it uses the same power it’s about as efficient as the 28W Kaby Lake R i7–8559U but half as efficient as 4·5W Kaby Lake m3–7Y30 and the two ultrabook CPUs and 1/3 to 1/4 as the top mobile CPUs.

I went to
CPUBenchmark.net to check and that CPU scores 968 points. Comments on the
FS-UAE performance page tell that ~900 points may be juuust enough to run the A1200 in cycle-exact mode with VSync although some more leeway is recommended. Ooof... A bit too close for comfort, but hey... Performance is reaching "interesting" levels!
So, I wonder if it can be concluded that the RPi 4 can manage this all the way for gaming and demos although just barely? Hmm, makes me wonder about heat and case recommendations since this board can get quite hot. I suspect one with both heatsink and fan would be recommended?
I suppose Amiberry will be faster (?) but on the other hand have a reduced feature set.
